If someone says "a name is very interesting" the meaning will depend on some more factors, such as tone of voice, facial expressions, body language, etc. However here are some common meanings for it.
1) "The name is different from most people." (The name can be something that can help a person stand out or be remembered. For example, I won't remember the faces of all ten people named Bill, but if someone is named Kenny, I am more likely to remember something about them)
2) "The name sounds like it is from a different country. Where is it from" (The name may sound non-native to the listener. For example, if someone is named Tsubasa, it does not sound like that are from America. I would be curious to know where they are from or where their name comes from. It is a great opportunity to tell others about the country you are from.)
3) "The name sounds like someone or something familiar." (The name can make someone think of something else or someone they know of in their life. For example, when some people hear the name Tiara, they may think of a crown, someone else they know with the same name, or even the Kpop group, T-ara, which is pronounced the same way.)
